High Quality Content by WIKIPEDIA articles! Voice or voicing is a
term used in phonetics and phonology to characterize speech sounds,
with sounds described as either voiceless (unvoiced) or voiced. The
term, however, is used to refer to two separate concepts. Voicing
can refer to the articulatory process in which the vocal cords
vibrate. This is its primary use in phonetics to describe phones,
which are particular speech sounds. It can also refer to a
classification of speech sounds that tend to be associated with
vocal cord vibration but need not actually be voiced at the
articulatory level. This is the term's primary use in phonology
when describing phonemes, or in phonetics when describing phones.
